The RACLAN box has been designed specifically for the superyacht industry.

The RACLAN box is an active safety box for the safe charging and storage of lithium-ion batteries, which are commonly found in water toys onboard. ​

The RACLAN box is fabricated from a high-tech composite material that is both waterproof, fire proof and explosion proof. The box is designed to store and charge batteries up to 3.5kWh.

Simply plug the box into your standard wall socket, place your battery inside and plug into the existing power supply located inside the box. Internally, the box incorporates an integrated hydrofluoric acid (HF) filter as well as 11 litres of extinguishing agent, should your battery enter thermal runaway whilst stored inside.
